i machines, and has for an object to provide a machine adapted fordigesting, draining, and drying refuse of any nature in a singlereceptacle and in practically a single operation.

A further object of the invention is to provide a refuse-reductionmachine wherein the refuse is taken in its ordinary or natural conditionand reduced to a dry and inodorous condition while continuouslyhermetically sealed, being dried'at a temperature so low as to reventignition:

further object of the invention is to pro vide a refuse-reductionmachine capable of angle-irons 21, extending longitudinally of reducing.to a dry condition refuse therein contained in the shortest possibletime and with a minimum expense and labor.

" mounted to rotate upon idlers and provided Specifically the object ofthe invention is to provide a jacketed cylindrical receptacle with meansfor the introduction of-live steam during the rotation for digesting thecontents, after which the surplus liquid 'is filtered off and thecontained air exhausted. Live steam is then admitted between thecylinder and its jacket to heat the cylinder for drying the contentsunder vacuum, the vapor passin away through the vacuum-pipe.

1th these and other objects in view the invention comprises certainnovel construction, combinations, and arrangements of parts, as will behereinafter fully described and claimed.

In the drawings, Figure 1 is a Vertical longitudinal sectional view ofthe improved reduotion-machine. Fig. 2 is a transverse sectional view ofthe machine, taken on line 2 2 1 of Fig. '1. Fig. 3 is a plan View ofthe perfo rate filter-bottom of the machine with the several constituentelements of said bottom so broken away as to show each. Fig. 4 is an.enlarged detail view of a fragment of. the rece tacle and jacket asshown at the lower si eof Fig. 2 and a transverse section of the partsshown in Fig. 3.

Like characters of reference designate corresponding parts throughoutthe several views. y

In its preferred embodiment the improved reduction-machine forming thesubject-matter of this application comprises a cylindrical receptacle10, concentrically secured within theijacket 11, spaced therefrom atoneend and completely around the said receptacle, except beneath theperforate bottom 12 formed in the receptacle. disposed within an openingin the periphery of the receptacle extending approximately throughoutits length and occupying a small circumferential arc. The said perforatebottom is composed of a plate 13, having openings or thimbles 14, uponwhich is disposed a late 15, having small perforations. with a filterfabric 16 secured upon the said plate 15 by means of the screen fabric17. The sev eral plates and fabrics are secured in position The bottom12 is by means of clips 18, clamped upon the frame 19 by means of bolts20 inserted through holes 21.

Within the receptacle 10 are secured the the receptacle and with onemember of said angle-iron extending radially and inwardly from the shellof the receptacle. 1 About the the perforate bottom and the jacket isseparated from the space between the jacket and thereceptacle, andcommunicating with the chamber thus formed is a pipe 23, provided with acook 24 for withdrawing surplus liquid from the said chamber which assesthrough the perforate bottom into said member.

For charging the receptacle manholes are provided formed by theupstanding bosses 25 about one or more openings in the top of the saidreceptacle and closed by the cover 26, secured in any approved manner,as by thelever -nuts 27 upon the pivoted eyebolts 28, About the openingcommunicating with the'said manhole a frame or liner 29 is dis osed,whereby the space between the jacliet and the receptacleis closed fromcommunication with the said manhole.

About the casing is secured the bands 30, carried upon idlers 31,'ournaled in. pillow blocks 32, secured upon sills 33 or in any otherapproved'manner. Opposite one of the bands 30 is secured a rack-ring34', en aging the pinion 35, mounted upon the sha 36, upon with theusualand ordinary cover and coverwhich a secured one of the idlers131, whichis rotated by means of the friction-clutch (shown conventionally at 37)and driven in ling 43 and with a steam-pipe 44, connected therewith atright angles and with a valve 45, arranged to control the flow of steamthrou h said pipe 44. The. pipe 39 is'continued by the pipe 46, intowhich .the valve 47 is introduced and which communicates with anyapproved source of pneumatic ex haustion. (Not shown.) At the endopposite the jacket is provided witha gland 48, through which extends apipe 49 into the space at the end between the jacket and the receptacle.Without the jacket the pipe 39 is provided with an elbow 40, having apacking-box 50, arranged in axial alinement with the pipe 39 and throughwhich extends a pipe 51, connected at its outer end with a steam-trap(shown conventionally at 52) and with its inner end depending within andadjacent to the-periphery of the jacket, as at 53. Connected with theelbow is also a steam-pipe 54, into whichis introduced the valve 55 forcontrolling the flow of steam therethrough, and a manhole or hand-hole56 securing means 1s provided in .the end ofthe jacket 0 tween thejacket and receptacle.

For convenience the terms bottom and top have been employed in thedescrip-- '.tion of this reduction-machine, it being understood that thesaid parts occupy such positions only when the cylinder is at rest forcharging or drawing off the surplus liquid and that at other times thecylinder ro-' 'tates.

sition shown in Figs. 1 and 2 by means of a jack-like screw 56-,bearing. against either one or both of the bearing-bands 30, and by,which means the cylinder is held ri idly in 'thesaid position and fromaccidenta rotary displacement. To charge the device, the -manhole-covers26 are removed and the refuse inserted therein in any approved mannerand by the use of any approved means.

When the approved quantity has been the manipulations of the va ve 45steam isadmitted through the pipes 39 and 41 'to the.

charged within the receptacle; the manholecovers are secured firmly inosition, and by receptacle, the other valves, as 47' and 55,

remaining closed. Power is then applied at the clutch 37 to rotate thecylinder and by r-obtaining access to the space be' reason of the steamtherein admitted and the agitation produced by the rotation and thebathe-plates 21 the contents is quickly digested. When sufiicient timehas elapsed for the thorough digestion of the, contents, the cylinder isstopped in normalposition and the cook 24 opened, which permits thesurplus liquid to flow through the pipe 23, being forced therefrom bythe steam admitted through pipe 44, being a pressfactu When the liquidhas ated by fluid pressure.

been drainedout tothe required extent, the valves 24 and 45 are closedand the valve 47 opened, whereby the air within the receptacle isexhausted through the pipe 46, pro-' ducing thereby a partia vacuumwithin the receptacle. pipes 54 and 49 to the chamber between the jacketand the cylinder, raising the temperature of the cylinder and itscontents thereby, and the vapor produced by the drying process passesofi through the pipes 41 and 46 into the vacuum-chamber. The water ofcondensation within the chamber between the jacket and. the cylinder isdrawn "off through the pipe 51 into the trap 52in the usual well-knownmanner. By the use .of this machine refuse of any and every nature maybe introduced therein thoroughly digested, drained, and driedwithout-leaving the cylinder and without opening the man- Steam is thenadmitted through i holes or any communication with the eXternal air: to.permit the escape of foul odors or contained figases, all of the vaporsand liquid passing 0 through the pipes as aforesaid and into the usualsewer or other connection.
